ST PORTC<7> data input.
RX
1
I
ST Asynchronous serial receive data input (EUSART module).
DT
0
O
DIG Synchronous serial data output (EUSART module); takes priority over
port data.
1
I
ST Synchronous serial data input (EUSART module). User must
configure as an input.
SDO⁽¹⁾
0
O
DIG SPI data out; takes priority over port data.
Legend:
Note 1:
DIG = Digital level output; TTL = TTL input buffer; ST = Schmitt Trigger input buffer; ANA = Analog level input/output;
x = Don’t care (TRIS bit does not affect port direction or is overridden for this option).
RD0 is the alternate pin for T0CKI/T5CKI; RD2 is the alternate pin for SDI/SDA; RD3 is the alternate pin for SCK/SCL;
RD1 is the alternate pin for SDO.
